The master/slave functionality is implemented using the analog inputs/
outputs.
The master enters the torque setpoint for the slave via an analog out-
put (terminals 75.x/15 or 16.x/15). Refer to Chapter 6.7).
Note
Master/slave operation is only possible for motors with encoders!

Warning
If, for a master/slave configuration, the rigid mechanical coupling is
